using namespace Spectre.Console function Invoke-SpectrePromptAsync { <# .SYNOPSIS Shows a Spectre.Console prompt. .DESCRIPTION This function shows a Spectre.Console prompt "asynchronously" in PowerShell by faking the async call. By allowing the prompt to run asynchronously in the background and polling for its completion, it allows ctrl-c interrupts to continue to work within the single-threaded PowerShell world. .PARAMETER Prompt The Spectre.Console prompt to show. .EXAMPLE $result = Invoke-SpectrePromptAsync $prompt #> param ( [Parameter(Mandatory)] $Prompt ) $cts = [System.Threading.CancellationTokenSource]::new() try { $task = $Prompt.ShowAsync([AnsiConsole]::Console, $cts.Token) while (-not $task.AsyncWaitHandle.WaitOne(200)) { # Waiting for the async task this way allows ctrl-c interrupts to continue to work within the single-threaded PowerShell world } return $task.GetAwaiter().GetResult() } finally { $cts.Cancel() $task.Dispose() } } |
